hadoop任务没有以伪分布模式进行

我尝试使用Hadoop，然后安装并可以作为独立模式使用 . 但是当我用作伪分布式模式时，会发生以下消息并且没有继续进行该过程 .

17/10/24 02:04:15 INFO client.RMProxy: Connecting to ResourceManager at localhost/127.0.0.1:8032

17/10/24 02:04:16 INFO input.FileInputFormat: Total input files to process : 10

我检查了localhost：50070并且有一个工作的Datanode . 我展示了我的设置程序 .

①安装Hadoop

brew install hadoop

②hadoop配置○libexec / etc / hadoop / core-site.xml

<configuration>
    <property>
        <name>fs.defaultFS</name>
        <value>hdfs://localhost:9000</value>
    </property>
</configuration>

○的libexec的/ etc / hadoop的/ HDFS-site.xml中

<configuration>
<property>
    <name>dfs.replication</name>
    <value>1</value>
  </property>
</configuration>

○的libexec的/ etc / hadoop的/纱线的site.xml

<property>
    <name>yarn.nodemanager.aux-services</name>
    <value>mapreduce_shuffle</value>
  </property>
</configuration>
<property>
    <name>yarn.resourcemanager.hostname</name>
    <value>localhost</value>
</property>

○的libexec的/ etc /的hadoop / mapred-site.xml中

<configuration>
 <property>
    <name>mapreduce.framework.name</name>
    <value>yarn</value>
  </property>
 <property>
    <name>mapred.job.tracker</name>
    <value>localhost:54311</value>
  </property>
</configuration>

③开始hadoop

sbin/start-all.sh

用jps

• ResourceManager

• NodeManager

• SecondaryNameNode

• NameNode

• DataNode

工作 .

④Hadoop的运行

hadoop jar libexec/share/hadoop/mapreduce/hadoop-mapreduce-examples-2.8.1.jar pi 10 100000

然后

Number of Maps  = 10
Samples per Map = 100000

17/10/24 02:04:17 INFO mapreduce.Job: Running job: job_1508778206216_0001

这个过程从未进行过 . 请告诉我它不起作用的原因 . 我访问了“http://macbook.local:8088/proxy/application_1508759907777_0001/ " to check Jobtracker, but an error code " ERR_EMPTY_RESPONSE” .
